A method for controlling the decelerated approach of an aerodyne on radio-alignment generally referred to as "glide," in particular for the purpose of reducing its fuel consumption and reducing the noise, mainly in the final stage of the approach, by approaching the glide at high speed, initiating the descent according to the glide angle, also at high speed then beginning a decelerated phase in order to reach a predetermined speed V sel+k, k being generally equal to 10 knots, on reaching a predetermined altitude, hF, and then passing progessively from the speed V sel+k to the speed V sel. From the time when the aerodyne reaches the axis of the glide path, a course is determined in two sections, as regards the variables of speed and altitude, for reaching the point situated at the altitude hF at the given speed V sel+k, namely a first section, at the beginning of which the aerodyne which was previously travelling along the glide, begins a first braking stage, the speed of the aerodyne, during this first section, bein reduced by at least a predetermined speed DELTA V1, and a second section, at the beginning of which the aerodyne initiates a second braking stage, the gradient dv/dh along these two sections having to satisfy the relationship P32=k P1 P1 and P2 being the respective gradients on each of the two sections and k being a value determined experimentally. |
